According to our results, the rental prices in Sydney have increased over time regardless of where students live. We recommend that the university provide more affordable housing options to make education more accessible and affordable for students.

Overview
This data was sourced from a survey containing 25 variables and was completed by 2103 students in DATA1901 and DATA1001 (99% of the cohort)
Our research focused on the variables: rent per week in AUD, Length of commute to campus (minutes), Cohort. We classified our variables quantitative continuous, quantitative continuous and qualitative discrete.

Limitations
Limitations of this data is that it is only a representation of this cohort and not a population so it will not accurately represent the fluctuating rent prices and commute times. There is a significant difference in cohort sizes for each semester, which can impact our data due to the different sample sizes.
It was assumed that people were honest and reasonable in their responses, and responses where students did not consent to take part in the survey were excluded. Students responded with the accurate amount of rent they paid in AUD$ per week, and also a reasonable estimate of the time it takes to commute to campus in minutes.
“$0” rent values were assumed to reflect students living with parents or family and were excluded, as they do not provide useful data about actual rent prices. Entries with rent values above “$2000” were also removed, as they could represent shared leases, data entry errors or luxury rentals not representative of student populations. Similarly, commute times were capped at 180 minutes (3 hours), a generous upper limit for reasonable commutes.
Research Question 1
How have rent prices changed between Semester 2 of last year (2024) and Semester 1 this year (2025) ?
